摘要:
A golf trainer (1) has a ground-engaging base (2) supporting a rail assembly (3) and a carriage (50) for guiding a golf club (typically a putter). Foot guides (12, 13) are of thin planar construction, having curved front edges and are configured and located to both indicate a good playing stance and provide support for the trainer (1) while the fronts of the player's feet are on them. The rail assembly (3) comprises a central post (25), and left and right side posts (26, 27). The base (2) comprises a central socket (30) for the central post (25), a left pair of sockets (31) for the post (26), and a right pair of sockets (32) for the post (27). The rail assembly (3) is secured to the base (2) by inserting the central post (25) in the socket (30), and simultaneously inserting the left post (26) in one of the sockets (31), and inserting the right post (27) in one of the sockets (32). By choice of socket, the user can secure the assembly (3) so that the stiffening web (21) is in a vertical plane, or has a configuration which is generally cylindrical about a vertical axis. A club carriage (50) comprises an elastomer grip (51) and a and a wheel (55) for rotation on the axle (54). The elastomer grip (51) comprises a central through-hole (56) for gripping the shafr, and the shape of the gripping element and of a connector (52) allow self-tightening in use.

The present invention describes a magnetic targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member having a steering material and is attached to the biocompatible device. The system also includes at least one anchoring member constructed and arranged for the inclusion of a magnetic material effective for influencing the traversal of the steering material, in vivo. The magnetically influenced anchoring member interacts with the targeting member such that the biocompatible device is positionable relative to the target area.

A video graphics controller (VGC) for communicating with a frame buffer memory and a display device includes a first-in, first-out (FIFO)-configured memory, a memory controller for communicating with the frame buffer memory and controlling the FIFO-configured memory, and read and write pointers for the FIFO-configured memory. A subtractor is coupled to the read and write pointers for generating a difference signal which is coupled to the memory controller, and the read pointer generates a read carrier signal which is provided to a lock detector along with an end-of-frame signal. The lock detector generates an output signal which is coupled to the memory controller in order to place the video graphics controller in a locked mode of operation if no read carry signal is generated during an inputting of an entire frame of information into the FIFO-configured memory, and in an unlocked mode of operation if a read carry signal is generated prior to the completion of the inputting of an entire frame of information.
摘要:
The present invention describes a system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member being constructed of, or having a steering material, which can be coupled to a biocompatible device. The system further includes one or more devices which are used to maneuver the targeting member into position prior to attachment of the biocompatible device. The biocompatible device is traversed into position through the passageway created by the targeting member and secured to one or more anchoring members.

The present invention describes a targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member that is attached to the biocompatible device and may optionally include a steering material. The system includes a passer element located at the distal end of a wand. The wand includes a trigger like member adjacent a hand grip. Actuation of the trigger like member will result in a pivotal movement of the passer element that positions the targeting member such that the connected biocompatible device is positionable relative to the target area.

The present invention describes a magnetic targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member having a steering material and is attached to the biocompatible device. The system also includes at least one anchoring member constructed and arranged for the inclusion of a magnetic material effective for influencing the traversal of the steering material, in vivo. The magnetic material is configured and sized so as to positionable external of the anchoring member, in vivo. The magnetically influenced anchoring member interacts with the targeting member such that the biocompatible device is positionable relative to the target area. An extender and connector have threads indexed to a securing set screw to facilitate positioning and affixation of the biocompatible material.

The invention describes a surgical implant that is equipped to provide neurological data during and after implantation. Neurological monitoring ensures accurate insertion of the implant with minimal disturbance of neural structures. The implant includes at least one electrically conductive region that is utilized to determine the distance from and direction to a nerve with respect to the implant.

The invention provides a connecting rod for bone anchors such as pedicle screws. The rod is constructed to include a main shaft portion that is not bioresorbable and a tip portion that is bioresorbable. The tip facilitates percutaneous insertion into a patient's body. After placement of the rod, the bioresorbable tip is resorbed preventing post-operative complications such as impingement of adjacent spinal facet joints.

A telescoping steering column assembly includes lower and upper jackets having inner and outer surfaces, respectively, disposed with respect to one another in telescoping relationship. The telescoping steering column assembly includes a linear bushing disposed between the inner surface of the upper jacket and the outer surface of the lower jacket, that includes a plurality of convolutions disposed axially in side-by-side relationship as viewed in cross-section to provide outer and inner load bearing surfaces to engage the upper and lower jackets and to provide radial walls for flexing to maintain the bearing surfaces in engagement with the jackets to allow the bushing to radially expand and contract. The present invention provides the length-wise grooves formed by the convolutions to allow for reservoirs for lubricant solution to help reduce friction between the jackets, wherein the convolutions are elastically deformed to adapt to the annual clearance between the jackets.

A graphics controller produces a composite image through selecting between input image pixels, which are designated to be displayed in the same pixel location, by using a select function. The select function is computed on a pixel by pixel basis to provide a select signal that indicates which pixel should be chosen for display as the final composite image on the display screen. The select signal uses mixing key functions to determine which pixel should be passed. The results of these functions are output in the form of key codes. Key codes are combined by performing a logical AND operation between the key codes, and with a Raster OPeration (ROP) code. The ROP code designates which key code combinations are to be logically ORed together to provide an increased number of possible key combinations to determine the selection of the image to be displayed.
